in reply to Passing $2 to a sub

You can't use $_ in stead of @_ like that. You want to change the subroutine to one of: 

sub createTable
{
  my $value = shift;
  print $value;
}

# or

sub createTable
{
  print $_[0]; # subscript means array
}

The $x syntax only works for @x variables when followed by a subscript in []'s. See perlvars for LOTS of details :-)
